Message

At Semicolon Africa, I develop backend systems with Java and Spring Boot, focusing on scalable architecture and efficient data management.

I streamlined data migrations across SQL, PostgreSQL, and MongoDB using Flyway, improving migration success rates by 20%.

I implemented test-driven development, improving code quality and reducing bugs by 15%. I also contribute to code and design reviews in Agile teams.

As a Software Engineering Intern at Semicolon Africa, I worked on API development and frontend integration, used Docker for containerization, and tested and documented APIs with Postman and Swagger. I also used Keycloak for authentication.
